Depression plagues many people, and its causes are mostly obvious. Loss of a loved one, trauma, and financial worries are just a few things that trigger these longstanding feelings of sadness. However, there are some little-known causes of depression that you may have overlooked. Here are a few, along with some helpful solutions.

Adrenal Fatigue

Today’s fast-paced world is very demanding, leaving many people in a constant state of stress, which causes the adrenal glands to continually pump out hormones to maintain the “fight or flight” mode. Unfortunately, this can lead to adrenal fatigue, which not only displays itself as physical tiredness, but also as depression. Schedule a checkup with a health care provider that understands this condition to see if it is affecting you.

Lacking in certain vitamins and minerals can cause a number of issues—including depression.


Low thyroid function or hypothyroidism is a common condition that often goes undiagnosed. If the thyroid isn’t working optimally, it slows down your metabolism and just about every bodily function. It causes weight gain, fatigue, dry and brittle skin, hair loss—and depression. When your body goes through all these issues, it’s little wonder that you’d feel down in the dumps. A doctor can check your thyroid level with a simple blood test and prescribe medication if needed.

Nutritional Deficiencies

As you already know, your body requires many nutrients to operate at peak performance. Lacking in certain vitamins and minerals can cause a number of issues—including depression. B vitamin deficiencies and lack of omega-3 fatty acids are major culprits. You can look into supplements or eat more vitamin-B rich foods like lean meats, eggs, bananas, and spinach. As for omega-3, salmon and other oily fishes are best.

Prescription Medications

You may not realize it, but depression is a side effect of many prescription medications. The acne medication Accutane and its generic equivalent both list depression as a possible side effect. Many cholesterol lowering drugs and high blood pressure medications also indicate depression among their side effects.
It’s a good idea to read up on the side effects of any medications you are taking. If you’re concerned about depression, talk to your physician about prescribing an alternative.

Seasonal Changes

You’ve probably heard about Seasonal Affective Disorder (SAD) causing depression during wintertime due to lack of sunlight. But believe it or not, the summertime blues are also a reality. It could be that your body is having trouble adjusting to the change of seasons. Lack of melatonin is often to blame. Supplements are an option, but you can also eat melatonin-boosting foods like bananas, oranges, sweet corn, and rice.
